Disney Tech Manuals from the 30's (II)

What I find particularly interesting about these manuals is the fact that the mechanics of animation was so closely linked to the mechanics of its recording. An animator would do a certain motion - a layout artist would draw the background and animation layout in a certain way - so it could be photographed, and preferably in the simplest way possible, though, this being Disney, that was not a goal in itself. What is more surprising, of course, is that we all still worked largely this way, even ten years ago. Still, the art without the mechanics - it cannot exsist. Here is the rest of the 1938 manual.
